Instead, Hippolite used social media to brag about his bank jobs — including one post he actually made before the heist, FBI officials said.

About 45 minutes before he robbed a Chase branch on Flushing Avenue in Brooklyn last July, Hippolite announced on his Facebook page “I Gotta Get that $$$$$ Man!!!!.” He was smart enough not to name the bank.

After another heist, a bank employe saw him get into a car and reported the plate number. The FBI and NYPD used the license plate reader camera system to find the car, and attached a GPS tracking device to it.

They checked the locations where the car — which belonged to Hippolite’s friend — had stopped. They turned out to be near 19 banks that had been robbed or reported attempted robberies, authorities said.
